Embodiment FIG. 2 is a main block diagram of a control section of an embodiment of the printer of the present invention. 10 is a microprocessor for controlling the printer; 12 is ROM and RAM;
A memory consisting of a control program that controls the entire printer, an address table T1 and a buzzer data table 2 illustrated in FIGS. 3 and 4, which will be described later, and a memory for arithmetic processing. be.

Reference numeral 13 denotes an I10 port, through which a buzzer device 159 and manual input device 16 are connected, and further through an interface control circuit to a host computer, etc., which is a host device.

The memory 12 stores an address table T1 and a buzzer data table T2 as shown in FIGS. 3 and 4, and the address DTI of the buzzer data table T2 is stored in the first address TA of the address table T1. The address DTO of the buzzer data table T2 is stored at the first address (TA+1). In this way, each time the address address goes up by one, the address DT of the buzzer data table T2 is added to the address table T1.
O, DT1. DT2. I remember DT3... The buzzer data table T2 stores data for setting the time to sound the buzzer and the time to stop the buzzer sound. In the example of the buzzer data table T2 shown in FIG. 4, the address of the buzzer data table T2 is “1” is stored in DTO, and the address DT
"4" is stored at the first position from O, and rOJ is stored at the second position.

Similarly, the address DT1 is "1", and the address DT1 is "1".
The first address (DT1+1) of I is "2", the second address (DTl+2) is "1", 3
"2" is stored in the address (DT1+3), and similarly, (DT1+4)=1. (DT1+5)=2.
(DT1+6>=1°(DT1+7)=O is stored.Similarly, each starts at address [)T1 to DTn, increases by 1 address each, and 1 at the address where "O" is stored.
constitutes a group. In this embodiment, the address table T1. Based on the data stored in the buzzer data table T2, management signal codes B511 to BSL3, alphabets A to 7, and numbers O, which will be described later, are used.
It is designed to ring a different bell sound corresponding to each letter such as 9 to 9.

For management signal codes BSLI to BSL, 3, the codes are determined in advance between the host device and the printer, and when the code is sent from the host device, the printer reads it and reads the code. It rings the bell sound corresponding to these, and these management signal codes B511 to B
SL3 can be used for various purposes such as notifying the end of printing, notifying printing interruption, notifying the occurrence of an error, and may be provided in any number depending on the purpose of use.

Next, the operation of the present invention will be explained with reference to the operation flow shown in FIG.

Data received from the host device via the interface control circuit 14゜I10 port 13 is transferred to the accumulator A.
(Step S1), the microprocessor 0 judges whether the contents of the accumulator A are the management signal codes B511 to BSL3 (Steps 82 to S4), and if the management signal code is BSLI, it is "1". If it is BSL2, store "2" in the index register R, and if it is BSL3, store "3" in the index register R (
Steps 85-87). Note that the index register R is initially set to "0" at the beginning. Next, the received data is the management signal code BSLI~BS
If not L3, buzzer code B to sound the buzzer
To judge whether it is EL or not, step S8), buzzer code BE
If it is L, proceed to step S12, and the buzzer code BEL
If not, determine whether the mode flag MF is “1” (
Step S9).

The mode flags M and F are reset to "0" in the initial setting, and are rewritten to "1" by a specific command from the host device.
0'', the routine shifts to the normal printer control routine (step 510), and normal 1 printing operation is performed. but,
If this mode flag MF is set to "1" by a specific command...(.

(Microprocessor-0 subtracts a certain number "y" from the contents of accumulator A, stores the value in index register IR, and performs so-called code conversion (step 511). For example, if the code is the code 65 of the alphabet rAJ, then subtract "y" from the code, for example, y=
61, "4" will be stored in the index register IR. In this way, the index register IR contains alphabets A to Z and numbers O to 9.
A new code obtained by subtracting the value of y from the character code will be stored. As a result, index register I
R is "0" by default, and the management signal code B511~
If BSL3 is input, "1" to "3" are stored respectively, and when the mode flag MF is "1" and a character code is received, a new code of "4" or higher corresponding to the character code is stored. It will be done. Next, the microprocessor 10 adds the first address AT of the address table T1 to the contents of the index register IR, reads the contents of the address of the added value, and reads the contents of the address of the added value, and reads the address of the buzzer data table T2.
step 512). That is, if the index register IR is "0", the address DTo of the buzzer data table T2 is changed from the address AT of the address table T1.
is stored in the address register ADR, and if the content of the index register IR is "1", the address DT1 of the buzzer data table T2 is stored in the address register ADR. Similarly, the buzzer data table T2
Addresses DTO to DTn will be stored in address register ADR. Also, microprocessor 1
0 sets the buzzer ON flag B and ONF to rOJ (step 512).

Next, the microprocessor 10 sets the buzzer ON flag BO.
It is determined whether NF is "1" (step 513), and since it is initially "0", the buzzer device 15 is turned off and the buzzer does not sound (step 514). Then, the buzzer data table T addressed by the address register ADR
Store the contents of 2 in accumulator A (step 8
16).

That is, to explain using the example of the buzzer data table T2 shown in FIG. 4, since the addresses initially stored in the address register ADR are DTO to DTn, "1" is stored in all the addresses. Initially, "1" will be stored in accumulator A.

Then, it is determined whether or not the accumulator A is rOJ (step 817), and if it is not rOJ, a timer T is set to a value obtained by multiplying the contents of accumulator A by 0 and started (step 818). The parameter n is set by the manual input device 16, and by changing the value of n, the length and interval of the buzzer sound can be changed by 1ffl. Next, wait until the timer ■ ends (step 19), add "1" to the contents of the address register ADR, and turn on the buzzer.
The flag BONF is inverted (step 520), and the processing from step 813 onwards is performed again. As a result, since the buzzer ON flags B O and N F are set to "1", the buzzer device 15 is operated to emit a buzzer sound (steps 813 and 515).

Then, the content of the address in the buzzer data table T2 indicated by the address register ADR is input into the accumulator A (step 816).

This time, the contents of address register ADR are “1” compared to last time.
” is added, the address of the buzzer data table T2 increases by 1, and when the starting address is DTO (when index register IR is rOJ), (DT
The data "4" at the address O+, 1) is stored in the accumulator, and when the starting address is DTI (when the index register IR is "1"), the data "4" is stored in the accumulator.
1-1), which is the data of address "2", will be stored.

In this way, the stored content of accumulator A is "0"
If not, set this value multiplied by 0 to the timer king and start it, and the timer king will be ゎ7t8-,,14
317,518). ；・）゛That is,
During this time, the buzzer continues to sound. Next, when the timer ■ ends, "1" is added to the address register ADR, and the buzzer ON flag BONF is inverted (step S20>, and the process from step 513 onwards is performed again. In this way, the process from step 13 onwards is transferred to the accumulator A. r
Repeat until OJ is memorized.

In this way, the content of the corresponding address in the buzzer data table T2 is read while incrementing one address at a time from addresses DTO-DTn of the buzzer data table T2 read from the address table T1 according to the value of the index register IR, and thereby the buzzer is activated. ON, OFF and their intervals are controlled, and finally, "0" is read from the buzzer data table T2, thereby ending one pattern of buzzer sounding operation. That is, if the buzzer code BEL is received when the index register IR is set to "0" in the initial setting, the address TA of the address table T1 is selected, and thereby,
The address DTO of the buzzer data table T2 is selected, the buzzer does not sound for one unit at first, and then the address (DT
O+1) is selected and the buzzer sounds for 4 units, and the content of the next address (DTO+2) is rOJ.
This operation ends. In addition, the signal code BSL for management
When the buzzer code SEL is received while the index register IR is set to "1", the address DT of the buzzer cheetah table T2 is received as described above.
1 is selected, the buzzer stops for 1 unit, sounds for 2 units, stops for 1 unit, sounds for 2 units, stops for 1 unit, sounds for 2 units, and ends. Similarly, when the mode flag MF is set to "1" and the character ]-do is received, an intermittent buzzer sound corresponding to each character code will be emitted.

In addition, when using character code, the buzzer data table T is set so that the beep sound signal is the same as Morse code.
If you set the contents of 2, you can use it for communication using Morse code.

In addition, in the above embodiment, the management signal codes B511 to
Although the BSL 3 is provided, a certain character code or a combination of character codes may be used as a management signal for printing end, printing interruption, etc. without providing these management signal codes. Roughly speaking, the buzzer sound is from the manual input device 16.
Since the length can be changed depending on the parameter n set in , the length of the buzzer sound can be set to suit various uses.

Further, in the above embodiment, an example of a printer is shown, but CR
Of course, it may be used for display devices such as T.

Further, in the above embodiment, the tone of the buzzer sound is one type, but a plurality of buzzer sounds with different frequencies may be provided, or buzzer sounds with different tones may be generated by a tone synthesis device or the like.

Effects of the Invention The present invention makes it possible to obtain a plurality of different buzzer sounds from the buzzer of a display device such as a printer, so it is possible to select the buzzer sound to be emitted from the host device, thereby preventing printing completion, printing interruption, or error occurrence. This buzzer sound can notify the operator of matters such as: Furthermore, by creating a one-to-one correspondence between characters and the corresponding buzzer sounds, it can also be used as Morse code.
